Full description

Our step-up dual dash cam: a sharp 4K eye in front, a second eye watching behind you. The Sister Eye Mark 1 records the road ahead in 4K and the road behind in 1080P at the same time, with a wide 160° view on both ends. It is the upgrade pick in our dash cam line — the one we point drivers to when they want the clearest plate detail, day or night.

4K front + 1080P rear: Two cameras, one system. The front records in 4K, the rear in 1080P, each with a wide 160° field of view.
Super Night Vision: An F1.6 aperture and 6-glass lens pull in more light after dark, so plates and signs stay readable at night.
Watch it on the screen or your phone: Built-in Wi-Fi connects to the companion app — review, download and share clips without pulling the card.
G-Sensor lock: A sudden impact locks the clip automatically so it can't be overwritten.
Loop recording: Recording never stops for a full card — the oldest clips roll off as new ones are written.
24-hour parking mode with time-lapse: Keeps watch while you're away and compresses parked hours into quick-review time-lapse clips.
Supports microSD cards up to 256GB: Use the card you have or add the size you want. Memory card not included.
